I wonder why this is r4600. I heard the Loongson2 is MIPS IV compatible,
so r5000 / r8000 / r10000 would be better choices.

I check the datasheet I have and i don't see loongson2e has implemented 
mips iv instructions.

Presently Loongson-2E is nearly MIPS III compatible(with some
self-defined extensions), next version will be mips64 release2 compatible.

-march=r4600 is inherited from loongson-1, -march=mips3 might be a
better choice.

I see.

Maybe. The 'mips3' maps to -march=r4000, it would assume more memory
latency and a slower integer divider then -march=r4600.

I don't really have an issue with that since I see it as a temporary
solution until gcc and binutils know about Loongson 2 specifics.  Given
the bit I know about the Loognson 2 processor architecture I would not
expect a significant performance boost from trying different values for
-march with current toolchains.

Just like Ralf has said, -march might not lead to significant
performance difference, but -mtune=
may. Two years ago, I found that adding a machine.def to descripe
pipeline and resources for loongson2
and -mtune=loongson boost many programs by 2-5%。
